Posejpal & Zwetschke was a firm in Kolín that built simple cyclecars from 1921 to 1923. It was run by two brothers-in-law who had previously worked for the firm Torpedo Trojan & Nagl. One of the vehicles competed in the Zbraslav-Jíloviště hill climbs in 1921 and 1922. The drivers Zwetschke and Feldman finished third in both events.
